Ayan instrument new type laboratory commonly used concentration equipment -- Automatic dry type nitrogen blowing concentrator!
Nitrogen blowing concentrator is also called nitrogen blow drying instrument, automatic rapid concentration instrument, etc., in the market generally there are two: dry nitrogen blowing instrument and water bath nitrogen blowing instrument.More and more people accept nitrogen blowers to concentrate samples instead of traditional rotary evaporators.Ayan independent research and development production of the new automatic dry nitrogen blowing concentrator, has been listed widely praised!
Principle:
We know that there are two ways to speed up evaporation: to strengthen the air flow around it and its temperature.Nitrogen is an inactive gas, which can isolate oxygen and prevent oxidation.The nitrogen blower USES the rapid flow of nitrogen to break the gas-liquid balance over the liquid, so that the liquid volatilizes faster.And through dry heating or water bath heating method to increase the temperature (the target boiling point is generally higher than the solvent), thereby achieving the purpose of concentration.
Operation:
The main components of nitrogen blowing apparatus mainly include gas distribution chamber, air needle, height adjustment bracket, nitrogen interface, height adjustment component, pillar, fixed component, cabinet, bushing, heating block, sample test tube or bottle, etc.After the installation of the nitrogen blower, the chassis is supported in the constant temperature water bath, turn on the water bath power supply, set the water bath temperature, and the water bath begins to heat.The nitrogen blowing apparatus is lifted, and the samples that need evaporation and concentration are placed on the sample positioning rack respectively, and are held up by the tray. The height of the tray and positioning rack can be adjusted according to the size of the test tube.Open the flowmeter needle valve, nitrogen through the flowmeter and the pipeline to the distribution disc, after distribution to the needle valve tube above all grades (installed on the distribution disc).Then, through the adjustment of needle valve tube needle valve, nitrogen through needle valve tube and needle blowing to the liquid sample test tube, you can adjust the lock nut can slide needle valve tube up and down, adjust the height of the needle, to blow ripples on the sample surface, the sample is not splashed.Finally, place the nitrogen blower in a water bath until evaporation and concentration is complete.
Advantages:
(1) more than one sample can be processed at a time, which has more obvious advantages in multi-factor and multi-level repeated experiments
(2) the experimental operation is simple and flexible.The enrichment process can be adjusted at any time without restriction
(3) in the experiment, the operator is not required to maintain for a long time, saving manpower
(4) nitrogen blowing instrument in the concentration of accurate, sensitive to avoid sample loss.Application of nitrogen blowing apparatus nitrogen blowing apparatus is mainly used for the purification and preparation of analytical samples by chromatography, mass spectrometry, etc. It is widely used for the volatilization of water, toluene, methanol, acetone and other solvents
Application:
(1) analysis of agricultural residues: such as vegetables, fruits, grains and plant tissues
(2) environmental analysis: such as drinking water, groundwater and contaminated water samples
(3) pharmaceutical testing: such as traditional Chinese medicine
(4) biological analysis: such as serum, plasma, blood, urine
(5) commodity inspection: inspection of dioxins, crotterol, etc
(6) food and beverage: such as milk, wine, beer, liquid drinks
